IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No. 1160,77 3, dated March 16,1875; appllcation tiled August 25, 1874.

Our drawing is a perspective view illustrating the construction and operation of our invention.

A represents the bar which forms the base and fra-me to support our mechanism. It is pivoted and balanced upon a suitable shaft, B, so that a vane at one end of it will keep it in line With the direction of the Wind. a a are ears projecting from the bar A to form bearings for the horizontal shaft b. cis a bevel-gcar Wheel rigidly attached to the right end of the shaft b. d is a vertical frame or bearer rigidly attached to project upward from the center of the base A, to support the governor. f is the governor spindle supported in suitable bearings in the frame d. g is abevel-gear wheel rigidly attached to the lower end of the spindle j'. It matches and engages the wheel c on the end of the horizontal shaft b. Adjustable balls are attached to the governor-spindle fin any known suitable way. Nos. l and 2 are skeleton frames of the sail-wheel of hexagon or octagonal form rigidly attached to the left end of the shaft b. h h represent a double series of fantail sails hinged to the outer edges of the wheels l and 2 in such a manner that they can be made to assume different angles relative to the horizontal shaft b, which forms the axle of the wheels. The outside No. 2 skeleton wheel or frame is larger than the N o. 1, and the sails h correspond accordingly. K is a rod pivoted to the sails h h, to link them together at their top and wide ends. Z is a rod pivoted to the lower end of the inside sail h, and to a collar, m, that slides on the shaft b. Each sail required to fill the wheels l and 2 is connected with the collar m in the same way. O is a frame rigidly attached to the left end of the base A to support a rockshaft, D. n a arerods rigidly attached to the rock-shaft D, and form a connection between the governor and the sliding collar m linked to the sails 7L.

In the practical operation of our invention, the piston-rod of a pump may be connected by bevel-gear, or any suitable mechanical devices may be employed to transmit power from our Wheel to drive machinery for various purposes.

A vane at the end of the base A Opposite to the saiLwheels will govern our Wheel relative to the direction of the Wind, and continually hold the sails in position to meet the force of the wind. A uniform breeze or blast will produce a uniform speed. Irregular blowing and force will be overcome by the weight Of the governor-balls, so that a superabundance of Wind-force will be expended in liftingthe balls. The blast strikes the pivoted sails, and turns them to angle away from the wind, and to let its force pass, and by so doing elevates the governor-balls` through the medium of the links lc and Z, sliding collar m, rods a, and rockshaft D. When the superabundant force has passed the sails h, the governor-balls will deseen-d, and again hold the sails in a vertical position.

A simple and complet-e means is thus provided to adjust the sails automatically relative to the force of the Wind to maintain uniform power and speed, and to prevent accidents in storms bythe blowing down and breaking of Wind-wheels.

' `We claim as our invention- 1. A wind Wheel composed of skeleton frames Nos. 1 and 2, and the two series of pivoted fan-tail sails L, substantiallyY as de scribed, and for the purposes specified.

2. The base A, having bearers a t and d, and frame O, in combination with the shaft b, gear-Wheel c, collar m, linked to sails It, and the rock-shaft D, and the governor mounted upon the spindle f, having a gear-Wheel, g, substantially as described, and for the purposes specified.
